I am still working out bugs with this new motor and everyweek it is something else. This week has got me kinda stumped.
I was driving the typhoon home for the holidays and was on the highway for a while and when i got off and into stop and go traffic i notice it was idling like crap. It would go down to about 500 and up to 1000 and just keep doing that at idle but if i gave it any gas it would run great. I got it home ok and the next few days the problem was sparatic sometimes it would idle and drive fine and others times it would go idle up and down. A few days past and when after driving it around for a while i would park it and leave it for like 20 minutes and when i came back it would not start it just kept cranking like it was either not firing or not getting fuel. I have had problems with the fuel pump before but i jumpped it and could hear it running so i knew it was not the fuel. I left it for a few hours and came back and did nothing other than turn the key and it started right up.
The next day I tried starting it and it was doing the same thing. Jumped the fuel pump and it was working. I hooked up a timing light and it was getting spark but the timing mark was way retarded like i was barely able to see it (tan wire disconnected) I just set my timing to TDC like a week ago and i tried to check if the distributor came loose but it was extremly tight.
Truck randomly started again and as long as it stayed above 1000 RPM'S it would run fine, let it drop below 1000RPM it would die. I drove it over to Jim Sloans house and we hooked up datamaster and it was picking up a code 42 There was never a check engine light while it was getting the code 42 on datamaster. We tried setting the distributor back to TDC but the problem was still there. So the balancer problem slipped because i can't see how the timing could have moved 30 degrees and i never noticed anything.
Anyway we got it to run and idle good just by moving the distributor around with the tan wire connected. The code is still there and i am going to need to find where DTC is again.
I read some old posts on the code 42 but found many people replacing a lot stuff with out any good results.
Jim noticed the 4 pin connector on the back of the distributor was routed badly and was in a bind and he feels like there is not a good conection between that and the ecm which seems very likely after reading about the troubleshooting procedure of the code 42.
Anyway i would like to know what everyone thinks about this. How do you think it happend in the first place? What would you replace first?
We did notice the cap terminals were showing arching signs on the what would be the retarded side, so it probably was running retarded but how, if the distributor was down tight?
This post is getting long I hope some of you had the patients to read it.
